People with borderline personality disorders, better known as BPD, show a deficiency in emotion regulation skills.
That might not sound like news but imagine getting so frustrated you wanted to smash your computer or scream really loud. If that did not suffice, would you hurt yourself or would you just let out a sigh of discontent and continue on with your day? People with BPD can’t always control their emotions and might cut themselves or cause harm to their bodies to deal with heavy emotional situations.
